Hi Idi,
I would suggest you to try multiple combinations :
1: Client Rev 48 - Studio Rev 56
2: Client Rev 56 - Studio Rev 48
3: Client Rev 48 - Studio Rev 48
4: Client Rev 56 - Studio Rev 56
I am also not sure which will work or which will not work for you.
Also Let us know "answer of Thomas Question"
Regards
Kumar.
